“Some argued that, even if the chance was small, she could one day be revived from her comatose state. In 2002, the Second District Court of Appeal requested additional EEG and CAT scans over the objections of her parents which confirmed no measurable brain activity and the presence of severe cerebral atrophy - from which there are no recorded instances of recovery, and which more doctors considered recovery to be a medical impossibility. Others argued that, whether or not she could be revived, her life should be preserved regardless. ”

“Following her death, autopsy showed her brain to have half the normal mass for a woman her age and confirmed the extensive damage shown on CAT scan.”
